useAnimate

Reactive Web Animations API.

Usage

Basic Usage

The useAnimate function returns the animation instance and control functions.

<script setup lang="ts">
import { useAnimate } from '@vueuse/core'
import { useTemplateRef } from 'vue'

const el = useTemplateRef('el')
const {
  isSupported,
  animate,

  // actions
  play,
  pause,
  reverse,
  finish,
  cancel,

  // states
  pending,
  playState,
  replaceState,
  startTime,
  currentTime,
  timeline,
  playbackRate,
} = useAnimate(el, { transform: 'rotate(360deg)' }, 1000)
</script>

<template>
  <span ref="el" style="display:inline-block">useAnimate</span>
</template>

Custom Keyframes

Either an array of keyframe objects, or a keyframe object, or a ref. See Keyframe Formats for more details.

import { useAnimate } from '@vueuse/core'
import { useTemplateRef } from 'vue'

const el = useTemplateRef('el')
// ---cut---
const keyframes = { transform: 'rotate(360deg)' }
// Or
const keyframes = [
  { transform: 'rotate(0deg)' },
  { transform: 'rotate(360deg)' },
]
// Or
const keyframes = ref([
  { clipPath: 'circle(20% at 0% 30%)' },
  { clipPath: 'circle(20% at 50% 80%)' },
  { clipPath: 'circle(20% at 100% 30%)' },
])

useAnimate(el, keyframes, 1000)

Options

The third argument accepts a duration number or an options object with the following additional properties on top of KeyframeAnimationOptions:

import { useAnimate } from '@vueuse/core'

useAnimate(el, keyframes, {
  duration: 1000,
  // Start playing immediately (default: true)
  immediate: true,
  // Commit the end styling state to the element (default: false)
  commitStyles: false,
  // Persist the animation (default: false)
  persist: false,
  // Callback when animation is initialized
  onReady(animate) {
    console.log('Animation ready', animate)
  },
  // Callback when an error occurs
  onError(e) {
    console.error('Animation error', e)
  },
})

Delaying Start

Set immediate: false to prevent the animation from starting automatically.

import { useAnimate } from '@vueuse/core'

const { play } = useAnimate(el, keyframes, {
  duration: 1000,
  immediate: false,
})

// Start the animation manually
play()
